ELECTRIC COOLING FAN COMPONENTS
INSPECTION
1. INSPECT ENGINE COOLANT TEMPERATURE
SWITCH
(a) Using an ohmmeter, check that there is no continuity
between the terminals when the engine coolant tem±
perature is above 93
C (199
F).
(b) Using an ohmmeter, check that there is continuity
between the terminals when the engine coolant tem±
perature is below 83
C (181
F).
If continuity is not as specified, replace the switch. 2. DISCONNECT ENGINE COOLANT TEMPERATURE
SWITCH CONNECTOR
Check that the cooling fan rotates.
If not, check the cooling fan relay, cooling fan, engine
main relay and fuse, and check for a short circuit
between the cooling fan relay and engine coolant
temperature switch.
3. CONNECT ENGINE COOLANT TEMPERATURE

ON±VEHICLE INSPECTION
Low Temperature (Below 83

C (181
F))
1. TURN IGNITION SWITCH ªONº
Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant
temperature switch, and check for a separated con±
nector or severed wire between the cooling fan relay
and engine coolant temperature switch.
High Temperature (Above 93
C (199
F))
4. START ENGINE
(a) Raise engine coolant temperature to above 93
C
(199
F).
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature switch.

ELECTRIC COOLING FAN REMOVAL
(See Components for Removal and Installation)
1. DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the 'LOCK'
position and the negative (±) terminal cable is discon±
nected from the battery.
5. REMOVE ELECTRIC COOLING FAN
(a) Disconnect the engine coolant temperature switch
connector from the radiator.
